VCP-IaaS Study Notes: Section 6.1

This is Section 6.1 in the VCP-IaaS blueprint Guide 1.2. The rest of the (completed) sections can be found here.

Identify where in the hierarchy a provider VDC resides

  • It right after the vSphere resources (vCenter,ESXi, Datastores and Networks)

Identify where an Provider VDC gets its resources

  • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
  • Click on the Provider vDC.
  • See the list of Organization vDC, Hosts, Datastores, External Networks and Resource pools.

Differentiate Provider and Organization VDCs

  • A provider virtual datacenter (vDC) combines the compute and memory resources of a single vCenter Server resource pool with the storage resources of one or more datastores connected to that resource pool.
  • A provider vDC is the source for organization vDCs.

Explain the concept of a Provider VDC

  • A provider virtual datacenter (vDC) combines the compute and memory resources of a single vCenter Server resource pool with the storage resources of one or more datastores connected to that resource pool.

Explain when and how to Enable/Disable a Provider VDC

  • You can disable a provider vDC to prevent the creation of organization vDCs that use the provider vDC resources.
  • When you disable a provider vDC, vCloud Director also disables the organization vDCs that use its resources. Running vApps and powered on virtual machines continue to run, but you cannot create or start additional vApps or virtual machines.
  • Procedure
    • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
    • Right-click the provider vDC name and select Enable or Disable.

Create/Delete a Provider VDC

  • Create:
    • You can create a provider vDC to register vSphere compute, memory, and storage resources for vCloud Director to use. You can create multiple provider vDCs for users in different geographic locations or business units, or for users with different performance requirements.
    • A provider vDC can only include a single resource pool from a single vCenter Server.
    • If you plan to add a resource pool that is part of a cluster that uses vSphere HA, make sure you are familiar with how vSphere HA calculates slot size. For more information about slot sizes and customizing vSphere HA behavior, see the VMware vSphere Availability Guide.
    • Prerequisites
      • Verify that at least one vCenter Server is attached with an available resource pool to vCloud Director. The resource pool must be in a vCenter cluster that is configured to use automated DRS. The vCenter Server must have the vShield for VMware vCloud Director license key.
    • Procedure
      • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
      • Click New Provider vDC.
      • Type a name and optional description.
        • You can use the name and description fields to indicate the vSphere functions available to the provider vDC, for example, vSphere HA.
      • Select the latest supported hardware version and click Next.
        • This selection determines the latest supported hardware version for virtual machines in organization vDCs based on this provider vDC. Hardware Version 8 requires ESX/ESXi 5.0 hosts. If this provider vDC will use a resource pool that contains ESX/Esxi 5.0 and ESX/ESXi 4.x hosts, select Hardware Version 7.
      • Select a vCenter Server and resource pool and click Next.
        • If the vCenter Server has no available resource pools, no resource pools appear in the list.
      • Select one or more datastores, click Add, and click Next.
        • vCloud Director does not support the use of read-only datastores with provider vDCs. In most cases, readonly datastores do not appear in the list, but some read-only NFS datastores might appear. Do not add these datastores to your provider vDC. Use only shared storage because vSphere DRS cannot migrate virtual machines on local storage.
      • Type the root user name and password for the ESX/ESXi hosts and click Next.
      • Click Finish to create the provider vDC.
  • Delete:
    • You can delete a provider vDC to remove its compute, memory, and storage resources from vCloud Director.
    • The resources remain unaffected in vSphere.
    • Prerequisites
      • Disable the provider vDC.
      • Disable and delete all organization vDCs and organization networks that use the provider vDC.
      • Procedure
        • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
        • Right-click the provider vDC name and select Delete.
        • Click Yes.

Select Resource Pools and Datastores for a Provider VDC

  • Add Storage Capacity to a Provider vDC
    • You can add storage capacity to a provider vDC by adding one or more datastores.
    • Procedure
      • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
      • Right-click the provider vDC name and select Open.
        • Click the Datastores tab.
      • Click Add/Remove.
      • Select a datastore from the list, click Add, and click OK.
        • vCloud Director does not support the use of read-only datastores with provider vDCs. In most cases, readonly datastores do not appear in the list, but some read-only NFS datastores might appear. Do not add these datastores to your provider vDC.
        • Use only shared storage because vSphere DRS cannot migrate virtual machines on local storage.
  • Add a Resource Pool to a Provider vDC
    • You can add additional resource pools to a provider vDC so that pay-as-you-go organization vDCs that the provider vDC provides can expand.
    • When compute resources are backed by multiple resource pools, they can expand as needed to accommodate more virtual machines.
    • Prerequisites
      • Verify that There is one or more available resource pool exists in the same vCenter datacenter as the provider vDC’s primary resource pool.
    • Procedure
      • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
      • Right-click the provider vDC name and select Open.
      • Click the Resource Pools tab.
      • Click Add Resource Pool.
      • Select the resource pool to add and click Finish.
    • vCloud Director adds a resource pool for the provider vDC to use, making all pay-as-you-go organization vDCs backed by the provider vDC elastic.

Explain when and how to Enable/Disable a Provider VDC Host

  • You can disable a host to prevent vApps from starting up on the host. Virtual machines that are already running on the host are not affected.
  • To perform maintenance on a host, migrate all vApps off of the host or stop all vApps and then disable the host.
  • Procedure
    • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
    • Right-click the provider vDC name and select Open.
    • Click the Hosts tab.
    • Right-click the host name and select Enable Host or Disable Host.
    • vCloud Director enables or disables the host for all provider vDCs that use its resources.

Prepare/Unprepare a Provider VDC Host

  • When you add an ESX/ESXi host to a vSphere cluster that vCloud Director uses, you must prepare the host before a provider vDC can use its resources. You can unprepare a host to remove it from the vCloud Director environment.
  • You cannot prepare a host that is in lockdown mode. After you prepare a host, you can enable lockdown mode.
  • Prerequisites
    • Before you can unprepare a host, you must disable it and ensure that no virtual machines are running on the host.
  • Procedure
    • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
    • Right-click the provider vDC name and select Open.
    • Click the Hosts tab.
    • Right-click the host name and select Prepare Host or Unprepare Host.
    • vCloud Director prepares or unprepares the host for all provider vDCs that use its resources.

Upgrade/Repair a Provider VDC Host agent

  • Upgrade:
    • vCloud Director installs agent software on each ESX/ESXi host in the installation. If you upgrade your ESX/ESXi hosts, you also need to upgrade your ESX/ESXi host agents.
    • Procedure
      • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
      • Right-click the provider vDC name and select Open.
      • Click the Hosts tab.
      • Right-click the host name and select Upgrade Host.
      • vCloud Director upgrades the host agent. This upgrade affects all provider vDCs that use the host.
  • Repair
    • If the vCloud Director agent on an ESX/ESXi host cannot be contacted, try to repair the host.
    • Procedure
      • Click the Manage & Monitor tab and click Provider vDCs in the left pane.
      • Right-click the provider vDC name and select Open.
      • Click the Hosts tab.
      • Right-click the host name and select Repair Host.
      • vCloud Director repairs the host. This operation affects all provider vDCs that use the host.

Explain when and how to Enable/Disable a Provider Datastore

  • You can enable or disable a datastore that has been added to a provider vDC. You must disable a datastore before you can remove it from vCloud Director.
  • When you disable a datastore, you cannot start vApps that are associated with the datastore or create vApps on the datastore.
  • Procedure
    • Click the Manage & Monitor tab and click Datastores in the left pane.
    • Right-click the datastore name and select Enable or Disable.
      • vCloud Director enables or disables the datastore for all provider vDCs that use its resources.+

Configure Low Disk Space Warnings
